題目:高分子材料電熱致動器
技術:材料力學
將導電高分子材料用模具做出上層U字形圖樣,基底用不導電材料製成。上層通電時因電阻發熱而膨脹伸長,基底因獲得的熱較少且熱膨脹係數不同而伸長較少,則兩者因伸長量不同而彎起。

Title : Polymeric Bi-material Electrothermal Actuator
Keywords : Mechanics of Marerials

Use electro-resistive polymer to apply U-pattern above nonconductive substrate. When applying electricity across the U-pattern, the upper part elongates because of resistance heat, and the substrate elongates less since lower temperature and different coefficient of thermal expansion. Because of the difference of elongation, the actuator bends.
